Joe: I guess it would be a good idea to define what these states are. My guess is that these are not states but "programs" specifying CPU behaviour. If Andreas is right about the granularity of the CPU changes to be down to 1 MHz, there are far more states. If you add to it the changes of voltages, you have even more states. Andreas and I are, as far as I can tell, in complete agreement on the definition of "what these states are". I certainly leave room for the possibility that I have just misunderstood what I've read of the 6 / 32 states ;). However, I clearly remember some AMD guy talking about how PowerNow! was better than SpeedStep, because PowerNow! had 6 throttle levels (with 32 to be introduced), whereas SpeedStep only had 2. This was quite a while ago, and as I've mentioned, I was unable to find a link to anything like that :( IMO the changes of just the multiplier would be good enough. Isn't changing FSB also messing with PCI and AGP cards? That's why I included the FSB+X option. Basically, there are two ways of getting around the problem you mention: - Using the memory bus clock for PCI and AGP. - Using FSB+X for PowerNow! states. The latter is already used in a FSB = MEMCLOCK+X in some Athlon (KT133) motherboards today. -fyo
